 communicate with all contactors, and battery management system, thereby managing energy flow between power supply, each of said two ESS, auxiliary system, propulsion system or DC-DC converters, including any combination thereof, at any given time of a given ride; 
 manage functionality of said two ESSs; 
 manage transformation of electrical power from one form to another; and 
 manage discharging, discharging or both of said two ESS;
